This dive site, Stora Knappen, is a notable step wall dive located in the northern part of the Väderöarna archipelago, Sweden. Divers navigate along a dramatic underwater wall that descends significantly, reaching depths of 35-40 meters at its base, though the maximum recommended diving depth for typical recreational diving is 21 meters. The site is known for potentially strong currents and significant swell, which adds to its challenging but thrilling nature.
The marine life at Stora Knappen is particularly rich in smaller, fascinating creatures. Divers can expect to encounter various crustaceans, including the interesting spider crabs and common edible crabs, alongside numerous species of nudibranchs, such as the vibrant sea lemon and the distinctive quadri liniata. Brittle stars are also commonly observed clinging to the intricate rock formations.
While specific peak seasons for Stora Knappen are not detailed, divers should always be prepared for cold water conditions typical of Sweden. It is highly recommended to visit with an experienced local guide who has a thorough understanding of the current patterns and local conditions. Due to the presence of strong currents and swell, this site is generally not suitable for snorkeling or freediving, making it primarily a destination for experienced scuba divers.
